The "Recently used coordinate reference systems" list is very handy for easily opening layers.

But sometimes a user can make a wrong assignment, and a useless CRS will be kept forever in his "Recently used coordinate reference systems" list.

In a StackExchange answer, Joseph point a simple solution (http://gis.stackexchange.com/questions/163938/clear-recently-used-coordinate-reference-systems/164141#164141):

*from PyQt4.QtCore import QSettings

QSettings().remove('UI/recentProjections')
QSettings().remove('UI/recentProjectionsAuthId')*

Could be useful for others users, not familiar with python, an option (button) in the GUI to clear his CRS list.
